2. MapStruct

MapStruct is a code generator that greatly simplifies the implementation of mappings between Java bean types based on the annotation approach. It is a Java annotation processor for generating the type-safe bean mapping classes.

All you have to do is to define a mapper interface which declares any required mapping methods. During compilation, MapStruct will generate an implementation of this interface. This implementation uses plain Java method invocations for mapping between source and target objects, i.e. no reflection or similar.

This is probably the simplest and quickest option for writing mapping code. It saves time by generating code which is generally tedious and error-prone to write your own.

Installing MapStruct

If you’re using Maven build tools, for using MapStruct framework you need to add the following package dependency

4. JMapper

JMapper is a Java bean to bean mapper framework based n Javassist framework. It allows you the ability to do dynamic mappings, multi-relational mappings, inherited mapping and other features without compromising on performance.

The framework allows you to map bean using annotation, XML or API-based configurations.

Installing JMapper

If you’re using Maven build tools, for using ModelMapper framework, you need to add the following package dependency
